DESCRIPTION

The MSA240 is a surface mount constructed PWM ampliﬁer

that provides a cost effective solution in many industrial applica-

tions. The MSA240 offers outstanding performance that rivals

many much more expensive hybrid components. The MSA240

is a complete PWM ampliﬁer including an oscillator, comparator,

error ampliﬁer, current limit comparators, 5V reference, a smart

controller and a full bridge output circuit. The switching frequency

is user programmable up to 50 kHz. The MSA240 is built on

a thermally conductive but electrically insulating substrate that

can be mounted to a heatsink.

TYPICAL APPLICATION

TORQUE MOTOR CONTROL

With the addition of a few external components the MSA240

becomes a motor torque controller. In the MSA240 the source

terminal of each low side MOSFET driver is brought out for

current sensing via RSA and RSB. A1 is a differential ampliﬁer

that ampliﬁes the difference in currents of the two half bridges.

This signal is fed into the internal error ampliﬁer that mixes the

current signal and the control signal. The result is an input

signal to the MSA240 that controls the torque on the motor.
